Which map uses the transverse Mercator projection?
The Universal Transverse Mercator (UTM) coordinate system and Gauss-Krüger coordinate systems are based on the transverse Mercator projection and the State Plane Coordinate System uses it for all north-south zones. Various countries use this projection for their topographic maps and large-scale coordinate systems.
How do Mercator projections distort countries?
The popular Mercator projection distorts the relative size of landmasses, exaggerating the size of land near the poles as compared to areas near the equator. This map shows that in reality, Brazil is almost as large as Canada, even though it appears to be much smaller on Mercator maps.
Which type of map projection is normally used for states in the US that are long in the east west direction?
Lambert con- formal conic
Lambert con- formal conic or other conic projections are often chosen for areas with a long east–west dimension, for example when mapping the contiguous 48 United States. Standard paral- lels are placed near the top and bottom of the continental area to reduce distortion across the region mapped.
Where does the Transverse Mercator project to and from?
It accurately projects to and from Transverse Mercator up to 80° from the central meridian. Because of the more complex mathematics involved, performance is affected. State Plane Coordinate System, used for zones that are predominantly north–south.
How are NAD83 Transverse Mercator County zones based on?
NAD83 Transverse Mercator County Zones are based on the GRS80 ellipsoid. Obviously, commercial software packages cannot be changed to handle this. Instead you can account for the use of the ellipsoid height by making some minor adjustments to the grid scale factor at the central meridian and the false northing and easting.
When did Lambert invent the Transverse Mercator projection?
Lambert did not name his projections; the name transverse Mercator dates from the second half of the nineteenth century. The principal properties of the transverse projection are here presented in comparison with the properties of the normal projection.
How is the Mercator projection similar to the Gauss Kruger projection?
Description The transverse Mercator projection, also known as the Gauss-Krüger projection, is similar to Mercator except that the cylinder touches the sphere or ellipsoid along a meridian instead of the equator. The result is a conformal projection that does not maintain true directions.
